Those unsearchable riches of your glory, Lord, were hidden in your secret place in heaven until the soldier’s spear opened the side of your Son our Lord and Savior on the cross, and from it flowed the mysteries of our redemption. Now we may not only thrust our finger or our hand into his side like Thomas, but through that open door may enter whole, O Jesus, into your heart, the sure seat of your mercy, even into your holy soul that is filled with the fullness of God, full of grace and truth, full of our salvation and our consolation. Open, O Lord, the ark door of your side that all your own who shall be saved may enter in, before this flood that overwhelms the earth. Open to us your body’s side, that those who long to see the secrets of your Son, may enter in and receive the sacraments that flow therefrom, even the price of their redemption.
–William of St. Thierry

Jesus notices us lost in our sinfulness, our isolation and confusion and greatly desires to take us to himself, even into his wounded side. And so the invitation is to honestly even joyfully take ownership of our very real need for mercy, our need to be found and sought out by him. Our sinfulness can never estrange us from Jesus, for as Saint Paul reminds us, nothing can “separate us from the love of God in Christ Jesus our Lord.” When we beg for Christ’s mercy, he will draw us into his broken Heart, because he loves us and wants to forgive and console us.
